# Eye Examinations, Oak Hospital Keywords: - [Oak Hospital](< /en/search?q=Oak Hospital >) - [eye diseases](< /en/search?q=eye diseases >) At Oak Hospital, we conduct visual field testing, photography, fluorescein and indocyanine green angiography, tomography, electrophysiological examinations, and intraocular pressure measurements. You need a physician’s referral for examination in our hospital. Sometimes we have to dilate your pupil with short-acting eye drops. Your vision may be slightly blurred after the ophthalmoscopy. Do not drive after the examination. We recommend that you arrive for your examinations and appointments using public transportation. Examinations and appointments may take some time, so please reserve plenty of time. Various examinations and procedures carried out during appointments cause changes to our schedules daily. ## [ Maisa Portal (opens in new window, links to another website) ](https://www.maisa.fi/maisa/Authentication/Login?lang=britishenglish) maisa.fi You can use our online services by signing in to the Maisa Portal.
